This is a rain seat cover. This black cover is made by Add-On and is designed to cover the driver seat, passenger seat and passenger backrest to protect it from rain and other things that fall from the sky. It has an elastic edge to fit snuggly on the motorcycle seat and will work great for traveling. It will fit with the outside mount backrests but, not with the type that mounts through the seat unless it has the quickout feature. This comes with a carrying case and will fit GL1800's as well as all GL1500's. 45-6965B
